Chobisika:Zotsatira zoyipa za hydroxypropyll methylcellulose ether patavala matope wamba owuma-owuma adaphunzitsidwa. Zotsatira zake zidawonetsa kuti: Ndi kuchuluka kwa zomwe zili pa cellulose, kusasinthika ndi kuchulukitsa kunachepa, ndipo nthawi yokhazikika idachepa. Kuchulukitsa, mphamvu za 7d ndi zotsutsana ndi zotsutsana ndi zinachepa, koma matope onse owuma asintha.

Mu 2007, mautumiki asanu ndi limodzi ndi mabungwe a dzikolo adatulutsa "chidziwitso choletsa kusakanikirana kwa matope m'mizinda ina mkati mwa malire". Pakadali pano, mizinda yonse 127 kudutsa ntchito "zoletsa matope omwe analipo", omwe abweretsa chitukuko chosanenedweratu mpaka matope osakanikirana. mwayi. Ndi chitukuko champhamvu cha matope osakanikirana ndi zomangamanga, matomini amatope owuma owuma nawonso atulutsanso mafakitale omwe amatulutsa, koma makampani ena amasungunuka amakokomeza mwadala mafakitale awo, osakaniza matongeki owuma. Kukula kwathanzi komanso mwadongosolo. Pakadali pano, monga asictiretures osakaniza a konkriti, matope osakanikirana owuma amagwiritsidwa ntchito limodzi, ndipo ochepa amagwiritsidwa ntchito okha. Makamaka, pali mitundu yambiri yazovomerezeka mu matiti ena osakanikirana, koma mu matope wamba osakanizidwa, palibe chifukwa chogwiritsira ntchito madongosolo ake komanso kugwiritsidwa ntchito mopitirira muyeso, ndikupangitsa zinyalala zosafunikira, ndipo zimakhudza mtundu wa polojekiti. Mu matope owuma-osakanizidwa, ethel etherse amagwiritsa ntchito gawo la kusungidwa kwamadzi, kukulitsa, komanso kusintha magwiridwe antchito. Zogwira ntchito bwino zamadzi zimatsimikizira kuti matope osakanikirana sangayambitse misampha, mafakiti ndikuchepetsa mphamvu chifukwa cha kusowa kwa madzi komanso simenti yokwanira ya simenti; Kukula kwa kukula kumathandizira kwambiri kulimba kwa matope onyowa. Pepala ili limatsogolera kafukufuku wadongosolo pa matope a cellulose mu matope osakanikirana, omwe akutsogolera tanthauzo la momwe angagwiritsire ntchito matope osakanikirana.
1. Zipangizo zopangira ndi njira zomwe zimagwiritsidwa ntchito poyesa
1.1 zopangira zoyeserera
Simentiyo inali P. 042.5 SETE, phulusa la Fly II kuchokera ku Taiyuan, chikondwerero cha Morespose ndi 2000 MPAREE).
1.2 Njira Yoyesera
Kukonzekera zitsanzo ndi kuyezetsa magwiridwe antchito kunachitika molingana ndi JCJ / T 70-2009 njira yoyesera yomanga matope.
2. Dongosolo loyesa
2.1 formula yoyeserera
Pa mayeso awa, kuchuluka kwa matoni amodzi a 1 toning matope owuma amagwiritsidwa ntchito ngati njira yoyambirira yoyeserera, ndipo madziwo ndi matope 1 osakanikirana.
2.2 dongosolo lapadera
Kugwiritsa ntchito fomula iyi, kuchuluka kwa hydroxypylpyl ethyllulose eter Ethethe pa kusungidwa kwamadzi, kusasinthika, kuwoneka kowoneka bwino, ndikukhazikitsa mphamvu yopanga matope owuma, ndikuwongolera, kutetezedwa kwachilengedwe ndi kupulumutsa mphamvu.
3. Zotsatira za mayeso ndi kusanthula
3.1 Zotsatira Zoyeserera
Zotsatira za Mlingo wosiyanasiyana wa hydroxypylropyl etherllulose kusungidwa kwamadzi, kusasinthika, kuwoneka kowoneka bwino, ndikukhazikitsa mphamvu ya matope owuma.
3.2 kusanthula kwa zotsatira
Zitha kuwoneka kuchokera kuzomwe zimachitika mu mankhwala osiyanasiyana a hydroxypropyl etherllulose chisungiko, kusasinthika, kuwoneka kovuta matope osakaniza. Ndi kuchuluka kwa ethel ether ether, malo osungitsa madzi a matope onyowa tsopano akuwonjezeka pang'ono, kuyambira 86.2% pomwe hydroxyprose celyl celyilose imasakanikirana. Kuwerengera kwamadzi kumafika 96.3%, yomwe imatsimikizira kuti madzi osungirako madzi a Proyl Methyl cellulose ether ether ether etheluluse etherose. Kusasinthika pang'onopang'ono kumachepa pansi pa madzi osungirako madzi a Propyl Methyl cellulose ethel ethel ethel ethel ethel ethel ethel ethel ethel ethel ethel ethel ethel ethel ethel ethel ethel ethel ethel ethel ethel ethel ethel ethel ethel ethel ethel ethel ethel ethel ethel ethel ethel ethel ethel ethel ethel ethel ethel ethel ethel ethel ethel ethel ethel ethel ethel ethel ethel ethel ethel ethel ethel ethel ethel ethel ethel ethel ethel ether (kumwa madzi patande) sikusintha The apparent density shows a downward trend, indicating that the water retention effect of propyl methyl cellulose ether increases the volume of wet mortar and reduces the density; Nthawi yokhala pansi pang'onopang'ono ndikuwonjezeka kwa zomwe zili hydroxypropyl celyl celyl ether ether ether etherch etherllupyl etherllulose nthawi ya matope otseguka; Mphamvu yovuta ya 7d ndi 28D yachepa (yayikulu kwambiri, yodziwikiratu yotsitsa). Izi zikugwirizana ndi kuwonjezeka kwa kuchuluka kwa matope ndi kuchepa kwa kachulukidwe. Kuphatikiza kwa hydroxypropyl methy cellulose ether amatha kupanga matope otsekeka mkati mwa matope owuma pakasupe matope. Microropes imathandizira kulimba kwa matope.
4. Kukwaniritsa kugwiritsa ntchito ma ethel ether mu matope osakanikirana
1) kusankha kwa cellulose ether ether. Nthawi zambiri, mafayilo ambiri a cellulose, madzi ake abwinobwino abwezera, koma mawonekedwe ake, ochepetsa kwake kususuka, zomwe zimawononga mphamvu ndi zomangamanga za matope; Chisangalalo cha cellulose ether ether ndiotsika matope osakanikirana. Amatinso zabwino zake, ndizosavuta kuti usungunuke. Pansi pa mlingo womwewo, amalimbikitsa zabwino, madziwo onse abweza.
2) kusankha kwa mlingo wa ethel ether. Kuchokera pazotsatira zoyeserera komanso kusanthula kwa zotsatira za zomwe zili ndi matope owuma, zimatha kuonedwa ndi mitengo yopanga cellulose kuti musankhe moyenera. Mlingo wa hydroxypropyl methy cellulose ethel ether-phonarly matope osakanizidwa Ngozi yabwino; Mlingo wa hydroxypropyl mankhwala cellulose ether ether ether clack clack-curser yopanda makilomita pafupifupi 3 kg / t.
3) Kugwiritsa ntchito ma ethel ether mu matope osakanikirana wamba. Pakukonzekera matope osakanikirana wamba, kuchuluka koyenera kumatha kuwonjezeredwa, makamaka posungira madzi ndi kukula kwake. Ngati itagwiritsidwa ntchito nokha kwa ethel ether, mphamvu yolumikizana singakwaniritse zofunika, ndipo kuchuluka kwa ufa woyenera wobwezeretsedwanso kumatha kuwonjezeredwa; Chifukwa cha kuchuluka kwa matope, cholakwika chokwanira ndichachikulu mukamagwiritsa ntchito nokha. Mtundu wa zinthu zouma zouma.
5. Malizitsani ndi malingaliro
1) M'matombi wamba owuma, ndikuwonjezera zomwe zili hydroxypyulose etheryllulodor etherlluloulose, kuchuluka kwa madzi kumatha kufikira 96.3%, kusasinthika komanso kanthawi kumachepetsedwa, ndipo nthawi yokhazikika imayamba. Mphamvu yovuta ya 28d idachepa, koma matontho onse owuma adasinthidwa pomwe zomwe zili hydroxypropyl celyl cely ether ether ether ether.
2) Pokonzekera matope osakanikirana wamba, ma cellulose omwe ali ndi mafayilo abwino komanso zabwino ziyenera kusankhidwa, ndipo mlingo wake uyenera kutsimikiziridwa kudzera pakuyesa. Chifukwa cha kuchuluka kwa matope, cholakwika chokwanira ndichachikulu mukamagwiritsa ntchito nokha. Ndikulimbikitsidwa kusakaniza ndi chonyamulira choyamba, kenako ndikuwonjezera kuchuluka kwa zowonetsetsa kuti zinthu zosakanizika.
3) Matope osakanikirana owuma ndi mafakitale omwe akutuluka ku China. Mukugwiritsa ntchito matope a matope, sitiyenera kuchita zambiri mwadzidzidzi, koma kulipirira kwambiri pazinthu zopangira, kulimbikitsa kugwiritsa ntchito zinyalala zamafuta, ndikuchepetsa mphamvu zonse.
